| 摘 要： | 采用倒扭摆内耗测试仪研究了Ｓｉ对Ｆｅ－Ｃｒ－Ａｌ减振合金阻尼性能的影响，结果表明：在Ｆｅ－Ｃｒ－Ａｌ中添加少量Ｓｉ（质量分数约为１％）或以Ｓｉ代替Ａｌ并经１２７３Ｋ及以下温度退火后，合金的阻尼性能（对数衰减率）优于Ｆｅ－Ｃｒ－Ａｌ，但经１２７３Ｋ以温度退火后，阻尼性能不及Ｆｅ－Ｃｒ－Ａｌ；以少量Ｓｉ代替Ｆｅ－Ｃｒ－Ａｌ中少量Ａｌ并经１３７３Ｋ以上温度退火空冷后，合金的阻尼性能比Ｆｅ－Ｃｒ－Ａｌ提高

| Abstract: | The effect of silicon on the damping capacity of Fe-Cr-Al alloy has beeninvestigated with the inverted torsion pendulum teclmiques. The results indicate that, smallamount silicon (app. 1% mass fraction) addition to Fe-Cr-Al or substitution of silicon foraluminum in Fe-Cr-Al alloy can make the damping capacity of the alloys higher than that ofFe-Cr-Al alloy when annealed below 1273 K; substituting silicon for small amount aluminum inFe-Cr-Al, the damping capacity of the alloy is much higher than that of Fe-Cr-Al alloy whenannealed above 1373 K followed by air cooling. The curves of logajrithmic decrement versus strainamplitude reveal the damping of the alloys resulting mainly from magonetomechanical hystereses. |
